FAA Advisory Circular 150/5300-13B — Airport Design (with Change 1)
Issuing body: FAA Office of Airport Safety and Standards (AAS-100). Jurisdiction: United States — civil airports. Advisory circulars are guidance, but 13B is mandatory for federally funded projects (grant assurances require compliance) and is the de facto national airport-design standard.
What it is
AC 150/5300-13B is the FAA's comprehensive airport-design standard: the US implementation of ICAO Annex 14 principles, translated into FAA-specific criteria. It consolidates what were previously separate ACs into one document covering runway, taxiway, and apron design; airport geometry (the runway design code / aircraft approach category + airplane design group system); safety areas (runway safety area, object free area, obstacle free zone); separation standards; navigational-aid siting; and — new in the B revision — Taxiway Design Group (TDG) methodology and updated fillet/lead-in standards. Any airport layout plan (ALP) approved by the FAA must conform to 13B.
Scope: who it applies to
Airport sponsors, consultants, and FAA planners/engineers designing or modifying civil airports — runways, taxiways, aprons, and associated safety areas. Triggers: new airports, runway extensions or new runways, taxiway reconfigurations (notably the FAA's taxiway-hot-spot mitigation program), ALP updates, and any AIP (Airport Improvement Program) grant-funded work.
Key requirements and compliance obligations
- Runway design code (RDC). Aircraft approach category (A–E, by approach speed) + airplane design group (I–VI, by wingspan/tail height) + visibility minimums — the RDC drives runway length, width, and safety-area dimensions.
- Safety areas. Runway Safety Area (RSA), Runway Object Free Area (ROFA), Runway Obstacle Free Zone (ROFZ), and Runway Protection Zone (RPZ) — dimensions by RDC; the FAA's RSA improvement program (post-2005) made RSA compliance a national priority.
- Taxiway design. TDG-based widths, taxiway safety area/object free area, separation distances, and the B revision's emphasis on direct-access taxiway elimination and angled/curved taxiway geometry to reduce runway incursions.
- Separation and clearance standards. Runway-to-taxiway, taxiway-to-taxiway, and taxiway-to-object separations by ADG/TDG.
- Declared distances and approach procedures. Takeoff run/accelerate-stop/landing distance available, coordinated with instrument-procedure design.
- Modifications to standards. Where 13B criteria cannot be met, the airport sponsor must obtain an FAA modification to standards — documented, safety-case-supported, and approved before construction.
Penalties and consequences of non-compliance
Advisory circulars carry no fines — but for AIP-funded airports, non-compliance means grant ineligibility and potential repayment exposure under grant assurances. FAA will not approve ALPs or find projects categorically eligible where design standards are violated without approved modifications. State aeronautics agencies mirror the AC in their own project requirements.
Version / edition status and live changes
- Current: AC 150/5300-13B with Change 1. The B revision (2022) consolidated the 13-series; Change 1 followed with corrections and updates. Flag (unverified detail): the exact Change 1 issuance date and itemised changes were not verified for this brief — confirm in the current AC text on faa.gov before citing.
- Live context: the FAA continues taxiway-safety initiatives (runway-incursion mitigation, wrong-surface landing prevention) that drive 13B-related design practice; Amendment 18 to ICAO Annex 14 (2025) will flow into future 13-series updates through FAA rulemaking.

- ACs are guidance with grant-conditional force; the binding obligations are in the grant assurances and Part 139 (for certificated airports), not the AC itself.
